Merge bitcoin/bitcoin#29496: policy: bump TX_MAX_STANDARD_VERSION to 3

Browse Source 
30a01134cd [doc] update bips.md for 431 (glozow)
9dbe6a03f0 [test] wallet uses CURRENT_VERSION which is 2 (glozow)
539404fe0f [policy] make v3 transactions standard (glozow)
052ede75af [refactor] use TRUC_VERSION in place of 3 (glozow)

Pull request description:

  Make `nVersion=3` (which is currently nonstandard on mainnet) standard.

  Note that we will treat these transactions as Topologically Restricted Until Confirmation (TRUC). Spec is in BIP 431 and implementation is in #28948, #29306, and #29873

  See #27463 for overall project tracking, and #29319 for information about relevance to cluster mempool.
